OIL-BURNER.

SPECIFICATION forming part of Letters Patent N 0. 755,340, dated March22, 1904. Application filed November 2,1903. Serial No. 179,633- (Ilomodel.)

To all whom, it may concern: P Be it known that I, JOSHUA M. YOUNGER, a

citizen of the United States, residing at Oakland, in the county ofAlameda and State of California, have invented certain new and usefulImprovements in Oil-Burners, of which the following is a specification.

My invention relates to improvements in oil-burners, the object of myinvention being to provide a burner for use in cooking stoves or ranges,heating-stoves, or furnaces which can be used either with thin grades ofcrude oil or with distillates and will convert the oil into gas andconsume the same without smoke, smell, or noise.

My invention therefore resides in the novel construction, combination,and arrangement of parts for the above ends hereinafter fully specified,and particularly pointed out in the claims. p

In the accompanying drawings, Figure 1 is a vertical sectional View ofthe apparatus shown as in use in a heating-stove. a plan view of theapparatus. View of the vaporizer. tive view of one of theair-tubesdetached.

Referring to the drawings, 1 represents a base-plate, which will vary inshape, according to the to be used. In the 3 is a plan present instanceI have shown it circular in form for use in a round heating-stove. Onthe center of said plate is cast a hollow boss 2, through which extendsthe feed-pipe 3. The upper end of said feed-pipe is threaded, as shownat 4, and on said threaded end is screwed the vaporizer 5. Saidvaporizer is of a general conical form and has a central chamber 6,through which the oil passes upward to the top, the oil then flowingover the top of the vaporizer onto a series of circular troughs orgrooves 7. These troughs increase in diameter downward, so that theouter edge of each trough lies over the trough next below it, so thatthe oil flowing over the top of the vaporizer drips into the troughbelow, fills the said trough, flows over the edge of said trough, andfills the next trough, and so on. At the bottom said vaporizer has awide circular rim 8, having a downwardly- Fig. 2 is Fig. 4 1s a perspec.

nature of the stove for which it is sloping outer edge 9. Upon saidsloping outer edge is supported the retort-casing 10, its lower edge 11being flared outward, as -shown,-the better to center the casing uponthe sloping edge 9. Said edge is formed with four vertical corrugations12, so that when the retort-casing rests thereon there are formed fourminute channels for the escape of the oil or gas generated. When the oilis first turned on, it drips through said minute channels onto aburner-plate 13, which is formed with concentric grooves 14, which theoil successively fills. This burner-plate 18 is supported on thebase-plate 1 by means of spacing-sleeves 15 and bolts 16. I Near theperiphery of the burner-plate are pivotally mounted, by means of. lugs19, arched air-tubes 20, the inner ends of which extend downward and areopen and shaped to abut looselyagainst the retort casing,.as shown. Theburner-plate is perforated, as shown at 21, immediately below the outerends of said air-tubes to supply air thereto. Air is thus supplied tothe burner in two ways, partly by passing between the baseplate andburner-plate and between the spacing-sleeves and partly by. passingupward through the air-tubes. In either case the air is heated beforebeing supplied at the point of combustion, in the former case by contactwith the under side of the inner edge of the burner-plate, which ishighly heated by reason of the flames being directed downward thereupon,and in the latter case'by reason of the flamespassing up around theair-tubes.

It will be understood that the space between the base-plate and theburner-plate may be adjusted to give a greater or less draft of air byremoving the spacing-tubes and substituting others therefor, longer orshorter, as may be desired. At a suitable distance from its center theburner-plate is'formed with an annular wall 22, which is formed withsquare notches 23, as shown, the better flames.

It will be seen that the base-plate and vaporizer thereon are concave orcontracted at their periphery opposite to the burner-plate to form anair-conduit around the edge of the burner-plate, said contracted portionpassing to distribute the Y through the central aperture in theburnerplate, and that the inner :edge of the burnerplate extends withinor nearer to the center than the gas-outlet from the vaporizer. By thismeans the air is brought into close contact with the hot vaporizer andis thoroughly heated before being supplied to the oil-vapor. Thus a muchbetter combustion takes place.

Should there be any. carbonaceous or other deposit upon the outside ofthe vaporizer, this can be easily removed by first throwing back theair-tubes on their pivots and then lifting the retort-casing, which maybe done by means of any suitable hook passed through an eye 2 L, formedor cast upon the top. After the surface of the vaporizer has beencleaned by a brush or otherwise the retort-casing isreturned to itsposition, and the air-tubes are thrown over on their pivots, so thattheir open ends rest against the outer wall of the retortcasing.

The operation of the device is as follows: When the oil is turned on, itflows up through the oil-supply tube over the upper edge of thevaporizer 5, fills the annular troughs 7, and falls into the concentricgrooves 1 L in the burner-plate,forming a thin layer of oil thereupon.When a suflicient quantity of oil has so flowed, it is lighted, and thecombustion of the oil thoroughly heats the retort-casing and thevaporizer, causing the oil therein to vaporize. After a sufiicient heathas been attained oil no longer flows through the minute channels 12,but gas emerges therefrom, which burns with complete combustion owing tothe air with which it is burned having been previously heated by contactwith the highlyheated burner-plate or by passing through thehighly-heated air-tubes.

I claim 1. In an oil-burner the combination of a base-plate, a vaporizersupported thereon at the top of which the oil discharges, a retortcasingclosed at the top and forming with said vaporizer a retort-chamber fromwhich the vapor is discharged downward, a burner-plate, having a centralaperture to surround the vaporizer, onto which the vapor generated isdischarged, and arched air-tubes for conducting air and discharging thesame downwardly onto said burner-plate in proximity to the place ofdischarge of the generated vapor, said tubes being arranged to be heatedby the flames of said vapor, substantially as described.

2. In an oil-burner the combination of a base-plate, a vaporizersupported thereon at the top of which the oil discharges, a retortcasingclosed at the top and forming with said Vaporizer a retort-chamber fromwhich the vapor is discharged downward, a burner-plate, having a centralaperture to surround the vaporizer, onto which the vapor generated isdischarged, and arched air-tubes for conducting air and discharging thesame downwardly onto said burner-plate in proximity to the place ofdischarge of the generated vapor,said tubes being arranged to be heatedby the flames of said vapor, and a serrated wall on said burner-platefor distributing the flames, substantially as described.

3. In an oil-burner the combination of a base-plate, a vaporizersupported thereon at the top of which the oil discharges, a retortcasingloosely supported upon the vaporizer and closed at the top and formingwith said vaporizer a retort-chamber from which the vapor is dischargeddownward, aburner-plate, having a central aperture to surround thevaporizer, onto which the vapor generated is discharged, and archedair-tubes for conducting air and discharging the same downwardly ontosaid burner-plate in proximity to the place of discharge of thegenerated vapor, said tubes being arranged to be heated by the flames ofsaid vapor, substantially as described.

5. In an oil-burner, the combination of the base-plate having a centralboss, the oil-supply pipe passing therethrough, the vaporizer screwedonto said pipe and resting on said boss said vaporizer being of ageneral conical form and having concentric troughs increasing indiameter downward, the retort-casing closed at the top and forming withsaid vaporizer a retort-chamber having a downwardly-extending opening,and a burner-plate spaced from the base-plate having a central openingto permit the air to pass therethrough, the flames dischargingdownwardfrom said opening onto said burner-plate, and pivoted arched air-tubesdischarging the air downwardly in proximity to the discharge of the gasfrom the vaporizer, substantially as described.
